Students should have a basic understanding of addition and subtraction as inverse operations, and/or that subtraction means you are "taking away" from a whole amount and addition is "putting together" to make a whole amount. Students who know several single-digit addition and subtraction facts, and doubles facts with sums as great as 20, will be able to apply these skills to feel more successful in the class. Students will learn through an "I Do, We Do, You Do" approach. I will begin with a...
Students will learn, show, and explain strategies to subtract 2-digit numbers using visual models, place value understanding, and number sense.
I'm offering this class to help students have a solid understanding of how to subtract numbers (and really think about the number being subtracted based on the place and value of the digits). For many students, subtraction always seems to be more difficult than addition. My goal in supporting students in their subtraction work is to encourage them to think more about the relationship of addition to subtraction, use number sense, and understand how they are taking a smaller part away from a larger part. This skill is foundational before students begin subtracting 3 and 4-digit numbers with additional place values. Understanding this skill will also help with division of a whole into equal parts and other math content areas where subtraction is applied. My content knowledge and experience in teaching young children about place value and subtraction has enabled me to understand how students need visual models and purposeful guided practice to conceptually understand this skill. I've had success using these specific strategies with elementary students throughout my years as a classroom teacher.
Students need to have paper, a pencil, and a few colored pencils or crayons. Students may also use a dry erase board and marker (but they will need at least 2 marker colors).
Learners will not need to use any apps or websites beyond the standard Outschool tools.
The learner is assessed through guided practice and independent practice, and also through their questions, comments, and responses.
50 minutes per week in class, and maybe some time outside of class.
